CRUSHING AND GRINDING lVlILL.

SPECIFICATION forming part of Letters Patent No.359,659, dated March 22, 1887.

Original appication filed December 19, 1885, Serial No. 186,071.

.To all wiz/077?, it may concern.-

Be it known that I, WILLIAM H. Bann, a` citizen of the United States, residing at Gallipolis, in the county of Gallia and AState of Ohio, have invented certain new and useful Im! provements in Crushing and Grinding Mills; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this My invention relates to grinding-mills for crushing and reducing earcorn, grain, feed, and fertilizers.

It consist-s in the novel features more fully hereinafter described, claimed, and shown in the annexed drawings, in which- Figure l is a perspective view, parts being broken away, ofa machine provided with my improvements. Fig. 2 is a detail sectional end view, parts being broken away. Fig. 3 is a detail section on the line X X of Fig. 1,`parts being broken away. Fig. 4 is .an enlarged view in elevation of the upper portion' of the cone-shaft and support, showing the means for adjusting the shaft and the cone mounted thereon. Fig. 5 is va plan viewof the shell, showing a section of one of the arms on thc line Y Y.

The frame of theimachine comprises cornerposts A, upper and lower side and end bars, B and O, respectively, and the table D. A mill of the cone shell and type is supported on one end of the table in the usual manner, and driven by a train of gear-wheels, the shafts of which project above said wheels, to afford a means for the application of a shiftable lever, I, having asocket-casting, t', to fit the ends of thelseveral shafts g, L,and n, provided with the intermeshing gear-wheels J, K, Z, and N, respectively,whereby speed may be applied as occasion may require. For grinding or crushing substances requiring great powersuch as ear-corn-the power is applied directly to the cone through its extended crank-shaft g by means of the lever I. When it is desired to grind substances not requiring so much power (No model.)

. Divided and this application filed May 15, 1856. Serial No and a higher rate of speed, the lever is applied to the shaft L. To obtain a still higher rate of speed, as when grinding fertilizers or similar substances not requiring great force, the power is applied to the shaft n by means of the lever l.

The several shafts have their upper bearings in a plate, E, of diamond shape, having an extending arm projecting frorn'one of its corners. In the outer end ot this corner the cone-shaft is journaled. rlhe other shafts are journaled one at or near the junction of the arm with the plate and the other inthe diametric opposite corner. In this manner the shafts are all in line.

rl'he shaft g, which may be an integral part of the cone, or separate and keyed thereto and projecting below the shell F, terminates in a crank, g2. above the bearingplate E, is threaded and provided with an adjusting collar, H, for regulating the distance between the cone and shell for various grades of grinding. Handles h2, extending from the collar, serve as a means for rotating the collar when adjusting it.

A pin, g', passing through one of a series of openings, It', obliquely formed in the collar at The upper portion, which extends' different levels, and extending into a vert-ical groove, g3, in the side of the shaft g, holds the collar inv adj usted position. The collar rests upon the arm of the .bearing-plate, and the latter is strengthened by a bracket or brace, g4, having its lower ends secured to the inside of the shell.

The lower end of the shaft gis supported by a stirrup, M, by which the cone can be independently adj usted, and for this purpose its ends are bent at right angles, threaded, pro` jected through the table, and provided with thumb-nuts m.

The shell is downwardly and outwardly dared from the medial line of the hopper and grinder, or the upper or hopper portionmay be separate from and fitted to the lower or grinderportion. The shell is provided with radial arms F, having anges f extending from their forward edges,with which the grain ICO shaft in an upward and inward direction, and the teeth on their under sides gradually grow longer as they recede from the shaft, and act in opposition to corresponding upwardly-projecting teeth, b, on the cone. The inside of the shell is provided with teeth b', which increase in thickness as they recede from the lower edge. Corresponding teetlnj, on the lower portion of the cone, diminish in thickness as they approach the base. The teeth may be straight or curved, the latter being preferred, as it gives the best results. Smaller teeth, f3, are interposed between the larger teeth, f2, on the cone to ll up the spaces which would otherwise be left.

A shaking-screen, O, is suspended beneath the table D by hangers o, of rubber, leather, chains, or other flexible material. Castings P,adj ustably connected to a pair of diagonallyarranged corner-posts,have pulleys or guides, over which passes a cord or rope, R, having its ends attached to diagonally-opposite corners ofthe screen, said cord being in connection with and operated from the crank gIz of the cone-shaft for giving the screen a side-to side motion. The screen and its operating and supporting devices, although referred to and shown in the drawings, do not forni a part of this invention, as the saine are shown, dcscribed, and claimed by me in Patent No. 342,166, granted May 18, 1886, of which this is a division.

The table near one end is transversely slotted, and is provided with a board, d, forming a chute for delivering grain, 82e., to the screen ,when it is desired to remove dust, Ste.

rlhe screen, as well as the lower side bars, is provided with guards U and T, respectively, to prevent the loss of grain.

From the foregoing description and the accompanying drawings, the operation of the machine can be readily understood; hence a detailed description is deemed unnecessary.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a grindingniill, the combination of a cone and shell, a train of gear-wheels, the shaft ofeaehwheelprojeeting upward abovethesanie, and an operating-lever adapted to engage any ofthe gear-shafts, whereby the cone may be driven at any desired rate of speed, substantially as and for the purpose set forth.

2. The combination ot' the cone and shell, tbc cone-shaft having a threaded extension and being slotted or grooved on one side, the adjusting-collar provided with a series ofopenings at different levels, and a pin or key adapted to be passed through either of the openings and hold the collar in adjusted posi4 tion, substantially as described.

3. The combination of the shell, the conc, the threaded cone-shaft slotted or grooved on one side, the adjusting-collar provided with a series of openings at different levels formed obliquely therethrough, and a pin for passing through either of the openings into the slotor groove in the cone-shaft, substantially as set forth.

In testimony whereof I afilx my signature in presence of two witnesses.
